and 18 with female threads 19.

The cap or closure plug 13 includes a diskshaped body having its circumference provided wi h male threads 20 for engaging the female threads of the cylindrical body and the inner end of the plug is tapered as at 21 to fit upon the tapered shoulder or seat 18 for forming a snug contact therewith so as to prevent the seeping of liquid from between the cylindrical body and the said plug or cap. The outer end oi the cap is provided with an annular flange which is adapted to fit upon the shoulder 17 for forming a further means for preventing the leakage of liquid from the said body. lhe axial center of the cap or closure plug is provided with a bearing 2C for receiving the drive shaft 2- which is (,letachably associated with the impeller wheel ltl. A suitable packing nut 25 is adapted to be thread ed on the cap 13 around the drive shatt 2': so as to effectively prevent the seeping of liquid from between said shaft and cap. The drive shaft Ql is utilized for operating a registering instrument 26 which is of the usual or any preferred character and therefore this registering instrument will not be described in detail. As shown, however, the registering instrument 26 embodies a cylindrical casing provided with a suitable sight opening 28 through which the counter cylinders 29 are adapted to appear. The drive shaft 24 extends directly into the easing 27 for engaging the operating mechanism for the said counter cylinders or disks 29.

In order to effectively hold the registering instrument 26 in place against accidental movement, the cap is provided on each side of its axial center with integral supporting lugs 30, and these lugs can receive screws 31 which can extend through the casing 27 of the registering instrument into the said lugs. It is thus obvious that the cap or closure plug 13 and the register 2-3 can be removed from the casting as a single unit.

The impeller wheel 16 includes a hub 3-3 which supports the radially extending helical blades 33 against whiclvthe liquid to be measured is adapted to impinge. These lades 33 are curved transversely as indicated by the reference character ill and as clearly shown in Figure l of the drawings. The hub ot the wheel it? has one end thereof provided with a suitable bore lor reeeiving the drive shaft Q-l: and this shat't can be detachably held in the bore by a set; screw 32 or the like. The opposite end oi the hub is provided with a conical bearing seat 35 in which is adapted to lit the conical end of a bearing pin 36 which is threaded into the end wall 12 at the axial center thereof.

this construction it can be seen that as the liquid flows through the casting or cylindrical casing ll, that the same will impinge against the blades or vanes 33 oi' the impcller wheel 16 which will cause the rotation thereel The rotation of the impeller wheel will in turn operate the drive shaft t l: through the medium of which is operated the registering instrument 26.

Thus it is obvious that by referring to the said register, the amount of liquid being dispensed through the casting can be readily seen.

The improved device is adapted to be iucorporated in a suitable pipe line and as shown, inlet and outlet pipes 37 and com municate with the inlet and outlet nipples ll and 15. In Figure 3 these inlet and outlet nipples 14: and 15 are shown provided with internal threads 39 for receiving the said pipes 37 and 3", but it so desired the same can be provided with external threads 39 as shown in Figure 8 of the drawings l'or permitting the use oi a coupling sleeve for connecting the pipes with the said nipples.

In Figure (3, I have shown a slightly modified form of the improved device in which the inlet and outlet nipples ll.- aud 15 are disposed in direct vertical alignment, and thus in this instance, the saidnipplcs communicate with the cylindrical body ll at opposite diametric points. ll hile the device will operate elliciently as shown in Figure 6 of the drawings, the preferred arrangement is shown in Figures 1 23 inelusive.

The cap or closure plug .3 can be readily attached to or removed from the casting or cylindrical body 11 by the use of a wrench as illustrated in Figure T of the draw 11].5. This wrench as shown, en'ibodies a shank 51, one end of which is provided with a rigid jaw wrench 52 for engaging the packing nut 25 while the opposite eiid thereol. is provided with oppositely extending la 'eraliy disposed arms oil and The arm 53 is provided with a hook :35 ha en gaging about one ol the lugs :1!) while the opposite arm is provided with a yoke 5H for straddling the other lug and for permiltiu; the vrench to turn thereon. ,It can be seen that when the yoke 50 is placed on one lug and the hook on the other, that a grip caii be readily obtained on the cap or closure plug for pern'iitting the easy turning there of.

Changes in details may bemadc without departing from the spirit or this invention.
